Embodiment Construction

[0021] The invention provides a method for optimizing the average sprinkling intensity of different combination intervals of straight-running sprinkling irrigation machines. In order to make the above and other objects, features and advantages of the present invention more comprehensible, preferred embodiments are listed below and described in detail in conjunction with the accompanying drawings.

[0022] Such as figure 1 As shown, first, the straight-running sprinkler 1 is selected as the test prototype. The model of the sprinkler 2 on the straight-running sprinkler 1 is Nelson D3000, and a rain gauge with a diameter D of 0.2 meters is arranged radially at the working place of the sprinkler 2. 3 is 11, used to measure the spraying water volume of a single nozzle. Set the working pressure of the sprinkler head 2 on the straight-running sprinkler irrigation machine 1 to 150kPa to keep the sprinkler head 2 in a stable working state. After the nozzle 2 has been working stably f...

Abstract

The invention provides an optimization method for the average sprinkling irrigation intensity under different combination separation distances of a straight walking sprinkling irrigation machine. Working pressure of spray heads of a straight walking sprinkling irrigation machine is set to guarantee that the straight walking sprinkling irrigation machine maintains a state of stable working. The range of a single spray head and water quantity distribution of spray heads are measured via tests; combination water quantity distribution under different combination separation distances of the spray heads is calculated; a profile map of sprinkling intensity distribution along the axis of a unit is drawn; an operating speed of the straight walking sprinkling irrigation machine is set; a total water receiving quantity and the average sprinkling irrigation intensity are calculated. The optimization method for the average sprinkling irrigation intensity under different combination separation distances of a straight walking sprinkling irrigation machine has the advantages of simple and rapid operation, can obtain more accurate calculation results with lower experimental costs and provide a direction and a basis for combination separation distances of spray heads in the straight walking sprinkling irrigation machine for follow-up study.

Description

technical field [0001] The invention relates to a calculation method related to performance parameters of a straight-running sprinkler irrigation machine, in particular to a method for optimizing the average sprinkler irrigation intensity of different combination intervals of a straight-running sprinkler irrigation machine. Background technique [0002] Straight-running sprinkler irrigation machine is a typical sprinkler irrigation equipment. The combination spacing of sprinklers on straight-running sprinkler irrigation machine directly affects its sprinkling intensity. The denser the combination spacing of sprinkler heads, the higher the sprinkling intensity. Conversely, the wider the combination spacing of sprinkler heads, the higher the sprinkling intensity. lower. Therefore, the setting of the nozzle combination spacing of the straight-running sprinkler irrigation machine is the key to ensure its effective operation. [0003] With the development of science and technolo...
